Step-by-Step Solution
Solution:
Step 1: Understand regression testing role in model updates
It verifies that updates do not cause performance drops or errors.Step 2: Exclude unrelated options
Speeding training, increasing data, or reducing features are unrelated to regression testing.Final Answer:
To ensure new model changes do not degrade existing performance or break workflows -> Option DQuick Check:
Regression testing protects model stability [OK]
Quick Trick: Regression testing guards model quality after changes [OK]
Common Mistakes:
- Confusing testing with training speed
- Thinking it changes data size
- Assuming it reduces features
